Declaration

The Margin property determines the number of pixels between the edge of the image (specified in the Glyph property) and the edge of the button. The edges that the margin separates depends on the layout of the image and text (specified in the Layout property). For example, if Layout is blGlyphLeft, the margin appears between the left edge of the image and the left edge of the button. If Margin is 3, three pixels separates the image and the button edges. If Margin is 0, no distance in pixels separates the image and the button edges.

If Margin is -1 (which it is by default), then the image and text (specified in the Caption property) are centered. The number of pixels between the image and button edge is equal to the number of pixels between the opposite edge of the button and the text.
